Starting/stopping the ramp-function generator
!
Caution
With the corresponding ramp-function generator parameter settings (e.g. offset),
the motor can “drift” and travel to its end stop.
The movement of the drive is not monitored while the ramp-function generator is
active.
To start the ramp-function generator:
1. Meet the conditions for starting the ramp-function generator
– Activate the control board
Drives -> Drive_x -> Commissioning -> Control board
– Switch on the drive
Control board -> Issue enable signals -> Switch on
2. Select the operating mode
e.g. speed setpoint downstream of filter
3. Select the drive (as control board)
4. Set the signal shape
e.g. square-wave
5. Load the settings to the target system (“Download parameters” pushbutton)
6. Start the ramp-function generator (“Start FctGen” pushbutton)
To stop the measuring function:
“Stop FctGen” pushbutton
